"This is such a great produce, I purchase for my husband as a gift, I received the item on a Wednesday, and his other hearing aid when out on him on a Friday, when I gave him his gift early instead of Christmas day, and he put it on and was able to hear me and the tv, he don't have to talk loud, he can hear himself and he don't talk loud or turn the tv up to max. He is deaf with 80% loss.Thank you! for making my husband happy and giving us a great Christmas."
